Solving
0.001 + -1x + x2 = 0

Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '-0.001' to each side of the equation.
0.001 + -1x + -0.001 + x2 = 0 + -0.001

Reorder the terms:
0.001 + -0.001 + -1x + x2 = 0 + -0.001

Combine like terms: 0.001 + -0.001 = 0.000
0.000 + -1x + x2 = 0 + -0.001
-1x + x2 = 0 + -0.001

Combine like terms: 0 + -0.001 = -0.001
-1x + x2 = -0.001

The x term is -1x.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1x + 0.25 + x2 = -0.001 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -0.001 + 0.25

Combine like terms: -0.001 + 0.25 = 0.249
0.25 + -1x + x2 = 0.249

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = 0.249

Calculate the square root of the right side: 0.498998998
